<p>PURPOSE:To narrow and straighten a written line and to process it by discriminating whether the difference between preceding coordinate data and current coordinate data in an A/D converting part is large or not to determine the line as a line parallel with the X axis or the Y axis or an oblique line and eliminating the noise component of image data to straighten the line. CONSTITUTION:When a writing pressure is applied to a tablet input part 12, X coordinate data and Y coordinate data of this depressed position are sent as the voltage signals of analog values to an A/D converting part 36, and the A/D converting part 36 converts inputted voltage signals to digital values. It is discriminated whether the difference between preceding coordinate data and current coordinate data of the input signal successively inputted from the tablet input part 12 is large or not to determine the line as a line parallel with the X axis or the Y axis or an oblique line, and the noise component of image data is eliminated in accordance with this determination result to straighten the line. The fluctuation or the like of lines at the time of input is suppressed to beautifully display image data due to hand-written input on a display part 13.</p> |
